Emirates Team New Zealand swung by a Friday evening race over three weeks ago after their seventh on the water session. Sail-World's camera caught the action as the AC72 reached down the back of Rangitoto and then gybed before getting up on her foils again for another run down the harbour.
Here we present an image analysis showing what foiling in an AC72 is all about - showing some of the points of technical interest, and track the process of foiling from start to full flight on one daggerboard and a single rudder.
IMG 8302 Flying down the back of Rangitoto. Note gennaker is fully sheeted and set. Goosewinged yacht indicates wind direction. Sea state indicates 12-14kt breeze. Boat speed estimated at 30kts - Emirates Team NZ September 14, 2012 - Richard Gladwell Click Here to view large photo
IMG 8346 - Emirates Team NZ turns downwind as leeward hull starts climbing, still building speed rapidly despite gennaker being seriously backwinded and not fully sheeted. Both foils are still down - Richard Gladwell Click Here to view large photo
IMG 8361 - Emirates Team NZ fully lifted on both foils, note the slimness of the hulls in this bow on shot. gennaker is still not fully drawing as apparent wind is still moving ahead. - Richard Gladwell Click Here to view large photo
IMG 8385 - Emirates Team NZ turns downwind and is close to paralleling the course of the keelboat sailing goosewinged and running dead downwind. Windward foil is retracted. Windward rudder has lifted clear of the water, but balance is maintained. - Richard Gladwell Click Here to view large photo
IMG 8417 - Emirates Team NZ at warp speed. Gennaker now drawing fully as it was in the image taken before the gybe (IMG 8302). ETNZ is still running near dead downwind, evidenced by the angle of the catamaran in the background, which is reaching across the breeze. - Richard Gladwell Click Here to view large photo
